A recording head in an inkjet recording apparatus forms an image on paper using ink. A first sheet of paper has first and second sides. A second sheet of paper has third and fourth sides. The recording head forms a first image and a first mark image on the first side based on first image data, and then a second image and a second mark image on the second side based on second image data. The first mark image represents a first reference location in a first rectangular region in which the first image is to be formed. The second mark image represents a second reference location in a second rectangular region in which the second image is to be formed. A controller determines an enlargement ratio of the second image to be formed on the fourth side based on a discrepancy between the first and second reference locations.

A printing apparatus including a set section on which a printing medium is set, a winding unit configured to wind, the printing medium transported from the set section, a head configured to discharge an ink onto an image forming surface of the printing medium being transported, thereby forming an image, and a drying chamber formed downstream of the head in a transport direction and downward of the head, the drying chamber being configured to dry the ink discharged to the printing medium, wherein the drying chamber is provided with an endless belt made of metal and configured to transport the printing medium while being in contact with an image non-forming surface on an opposite side of the printing medium from the image forming surface, and a plurality of rollers over which the endless belt is stretched, the plurality of rollers being configured to cause the endless belt to rotate.

A printing apparatus includes a printing unit that performs printing on a print medium with a sheet shape, a medium feeding unit and a medium winding unit that conveys the print medium in a predetermined conveyance direction, a controller that controls the printing unit, the medium feeding unit, and the medium winding unit, and a shaft that winds the printed print medium. The controller includes a cutting position determination unit that determines a cutting position to cut and separate the print medium in the width direction upstream by a predetermined length from the end of the image of the first print surface in the conveyance direction, and the cutting position determination unit determines the cutting position so as to cut upstream from the end with an increase in the circumferential length of the print medium wound around the shaft.

A label printing device includes: a conveying unit configured to convey a mountless label; a shaft portion configured to change a conveying direction of the mountless label; a cutting unit configured to cut the mountless label of which the conveying direction is changed by the shaft portion and issue a label; and a controller configured to control the conveying unit and the cutting unit. The controller executes a preparatory operation mode in which the mountless label is conveyed a predetermined distance longer than a length of a portion extending from the shaft portion to the cutting unit in the mountless label by the conveying unit and is cut by the cutting unit when a label is not issued for more than a predetermined time.

A medium wind-up device is provided to suppress causing a wrinkle at a time of winding a medium, and also suppress a fluctuation of a winding position. The medium wind-up device includes: a tension roller that presses a medium, which is belt-shaped and transferred in a transfer direction that is predetermined, in order to provide the medium with a tension; a reversing roller that reverses the medium pressed by the tension roller, and the reversing roller being rotatable so as to follow a move of the medium; a loading mechanism that is capable of placing a load against a rotation of the reversing roller; and a wind-up portion that winds up the medium reversed by the reversing roller.

Provided are a transport device and a printing device configured to minimize fluctuation in a tension of a medium in a portion between a first transport unit and a second transport unit. A transport device provided to a printing device includes a transport mechanism serving as an example of the first transport unit, a winding unit serving as the second transport unit disposed downstream of the transport mechanism in a transport direction, a tension imparting unit provided with a tension bar serving as an example of a tension imparting member biased toward a medium between the transport mechanism and the winding unit and configured to impart tension to the medium, and a biasing force adjustment unit serving as an adjustment unit configured to adjust at least one of a biasing force of the tension bar and a relative speed between the tension bar and the medium.

A printing apparatus (printer) is provided in which a base material is conveyed by a roll-to-roll method and feedback control is performed on a tension imposed on the base material, and which includes a control unit, a first drive motor (front drive motor) configured to control a speed of conveyance of conveying the base material, and a second drive motor (feeding motor, rear drive motor, winding motor) configured to control the tension imposed on the base material. In a case where a conveyance operation for conveying the base material is stopped based on detection of a foreign object, and when a speed of the first drive motor is at a predetermined value or less, the control unit stops the tension control performed by the second drive motor.

A conveyance device includes a support having a support face configured to support a conveyed object and a fluid introduction device disposed outside the support. The fluid introduction device is configured to introduce a fluid between the support face of the support and the conveyed object, to form a fluid layer for floating the conveyed object. The conveyance device further includes a conveyor configured to convey the conveyed object being floating from the support via the fluid layer.

A contacting member is provided that contacts a region of a contacted member to which a liquid composition has been applied. The contacting member has a fluororesin fiber layer containing a fluororesin fiber, which is disposed on a surface which contacts the contacted member. The fluororesin fiber layer has an average deformation amount of from 5.0 to 18.0 m/N, which is calculated from a displacement amount obtained when a circular indenter having a diameter of 5 mm is pushed into the fluororesin fiber layer.

In a printing apparatus, a controller is configured to control a printing unit such that printing is started after a transport distance of the substrate reaches a pre-discharge transport distance, in which the pre-discharge transport distance is set to a value not less than a first longest distance, provided that a transport distance in a condition in which the transport distance is a longest distance among conditions 1, 2, and 3 provided below is the first longest distance. Condition 1: a transport distance until a region of the substrate that was nipped between a front driving roller and a nip roller passes through a printing head disposed most downstream in a transport path of the substrate, Condition 2: a transport distance until a transport speed of the substrate becomes constant, and Condition 3: a transport distance until tension of the substrate being transported becomes stable.
